Full methodology ›The read
Keystone, South Dakota (ZIP 57751) ranks in the top 14.7% healthiest ZIPs nationally (4,700th) and the top 5.0% of South Dakota (18th).
Several signals sit on each side of the ledger here: park land settles in the top 1.0% nationally, and modeled tree cover rests in the top 3.0% nationally. Modeled short sleep lands in the bottom 6.5% nationally, and humid heat settles in the bottom 7.2% nationally. Modeled cognitive disability rests in the bottom 7.8% nationally, distance to a hazardous-chemical facility lands in the top 10.9% nationally, and modeled tooth loss settles in the bottom 10.1% nationally. Working the other way, crowded housing rests in the top 3.8% nationally, modeled fine-particle lands in the top 11.7% nationally, and slow internet speeds settles in the top 12.7% nationally.
Against its neighbors, park land runs far higher than the surrounding ZIPs on this measure. For context, distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. The closest ZIP that ranks healthier overall is ZIP 57702, just across the boundary.

How these were chosen: only ZIPs with a published Score appear — a nearby ZIP with too little data to score won’t. Nearby means closest by distance between ZIP boundaries, which can cross state lines. A similar health profile is a close match across the nine Score domains, not similar demographics. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

About the ± — it’s this estimate’s give-or-take (statisticians call it the standard error). The true life expectancy for this ZIP most likely falls within 2.31 years of 82.3, and it’s very unlikely to be off by more than twice that.

How these lists were built: they draw only from ZIPs that have a published Score, so ZIPs with too little data to score are not listed. Distance-based lists use distance between ZIP boundaries with no state filter, so an out-of-state ZIP can appear. Statistically similar means a close match across the nine Score domains, not a demographic match: the measure is the cosine similarity between two ZIPs’ domain scores, taken over the domains both ZIPs have data for and only where that overlap covers at least six of the nine — and where no ZIP clears that minimum-overlap floor, that list is left out rather than filled with a weak match.
